Application led Augustl 26, 1929. SerialY No. 368,477.

rlhis invention relates particularly `to .a means for dispensing predetermined lengths of vpaper from a roll ina closed container.

The object of the invention is to provide a simple coin controlled paper vending machine that will be economical to manufacture, of f ew parts, easily operated, strong, durable and highly efficient in its practical application.l 4

In the drawings: v

Figure 1 is a front elevation of the device with the closure raised.

Figure 2 is an end elevation of the'same with the closure closed.

Figure 3 is a section on line 3-3 of Figure 1. f

Figure 4 is an enlarged detail of the coin controlled actuating mechanism, parts broken away and partly in section.

rhe case 1 is provided with a hinged closure 2 provided with locking means as at 3. In the case are mounted vertical standards l havino a roller mounted at 5 for, carr in@v a roll of paper, and a pair of feeder rolls as at 6 and 7. A slot 8 is formed in the case below the feeder rolls.

In one end of the case is mounted a plate 9 having a hub 10 extending through the case and having a cam surface 11 formed on its outer end ending in an abrupt shoulder 12.

At 13 is a hand wheel mounted on a spindle 14e which has a reduced portion 15 revolubly mounted in the hub 10 and carrying a plate 16 to rotate upon the inner surface of plate 9. A cam surface 17 is formed in the shoulder 18 and ending in an abrupt shoulder 19 in opposed relation to the cam surface and shoulder 11 and 12 of hub 10 as shown.

In the spindle 14. is formed a bearing 2O to receive a shaft 21, a spring 22 being inserted between the end of the shaft and the end of the bearing to normally hold the opposing cam surfaces 11-17 in spaced relation to each other and to normally hold the plate 16 in contact with plate 9.

On the shaft 21 is mounted a gear -23 meshing with a small gear 24 on one feeder roll as 6, the ratio between the circumferences of the gears and rollers being such that one complete turn of the shaft- 21 will rotate the feeder' rolls to deliver a predetermined length of paper. On shaft 21 is also mounted .a bar 25 having a pin 26 set therein to engage holes 2l' and 28 in plates 16 and9, and on the op.- posite sides of the shaft to pin 26 is` formed a slot 29 open on itsouter end and on the edge toward plate 16. A spring 30 is inserted between the bar 25 and gear 23, and a coin chute 31 is mounted in the case with an entrance at 32 and positioned to discharge into. slot 29 at end 33. p y

With a roll of paper mounted as at y34 and having an end extending downwardly between the feeder rollers 'and kthrough slot. 8,

the device, cannot normally be operated ,tov

feed .additional paper because of the engage-y -V nient between Athe plates 16, and v9 through the medium` lof pin 26.A lfhen, however, :a coin is dropped into slot29 the pin 26. may be withdrawn from the fixed plate 9 by shoving the hand wheel inwardly, this movement causing the plate 16 to.V move inwardly and, through the medium of the coin, 35, to

move the bar 25 inwardly'togetlier with the pin 26 mounted therein.v The wheel 13 now A being rotated the coin drops outJ into the case on the half turn but the pin rides. upon. the surfaceofplate 9untila' complete revolution of the wheel has been made when it automatically drops back into the hole 28 and the device is rendered inoperative until,` another coin isy droppedV into,` place. The .engagement atl 36 renders member 14 rotationally fixed but longitudinally movable? on member 21.

The engaging cam surfaces. 1].-17 automatically withdraws the plate 16 from'` contact with the coin as thewheel is turned; therebyV permitting the coin to fallI out of the slot at the proper time and eifectually preventing the operator-v from carryingxthe coin around aV second time.i

It is to beunderstood, of course, thatfwhile 1 haveherein .shown and described but one y specific embodimentof the invent-ion, .changes in form, construction, and method of assem: bly and operation may bemade. within. the scopeA of; the appended claims.

chine comprising, a case having a slot formed therein, a pair of feed rolls mounted therein in operative relation to the slot, an operating shaft mounted therein and driving connections between the shaft and rollers, actuating means for the shaft resiliently mounted thereon for axial movement relative thereto but rotationally fixed relative thereto and op erable from the exterior ofthe case, a plate mounted on the inner end of the actuating means, a bar revolubly mounted on the shaft, resilient means for urging the bar toward the plate, a pin mounted in the bar and directed toward the plate, the plate and case having alignable orifices formed therein to receive the pin, and the bar having a slot formed in the end thereof remote from the pin adaptedto receive a coin and support the same in contact with the said plate, means for introducing a coin into the slot from the exterior of the case, and means for releasing the inserted coin during rotation of the shaft.
